Systems for grind duration adjustment for grinders

Abstract

A grinding system that includes a grinder attached to a grind size adjustment ring. Also, a potentiometer attached to the grind size adjustment ring, so as to provide a grind size measurement to a controller. The controller selects a grinding duration based upon the selected grind size measured by the potentiometer.

What is claimed is: 
     
       1. A system, comprising:
 a grinder, comprising an upper annular ring and a lower annular ring; and 
 a controller, configured for choosing a grind duration based upon a grind size value; 
 an optical sensor, coupled to the upper annular ring and the lower annular ring, configured for measuring a distance between the upper annular ring and the lower annular ring; and 
 wherein the distance corresponds to the grind size value. 
 
     
     
       2. The system of  claim 1 , wherein the optical sensor comprises one of a photoelectric sensor and a linear sensor. 
     
     
       3. The system of  claim 1 , further comprising:
 a sensor line connected between the controller and the optical sensor. 
 
     
     
       4. The system of  claim 1 , further comprising:
 a grind size adjustment ring configured for changing the grind size value of the grinder. 
 
     
     
       5. The system of  claim 4 , further comprising:
 a potentiometer rotatably coupled to the grind size adjustment ring, 
 wherein the potentiometer is configured to output the grind size value, based upon a measured rotation of the grind size adjustment ring.
